On 1st February 1886, the Cardiff Coal Exchange was formally opened.  At one time it determined the price of coal throught the world and is reputedly where in 1901, the world's first million pound business deal was made.

Cardiff was at one time, the biggest coal port in the world and the Coal Exchange in Mount Stuart Square was where mine owners, agents and ship owners met to conduct their business, with up to 10,000 people passing through its doors every day.  However, the coal industries downturn, led to the Coal Exchange closing in 1958.

In 1979, it was to be the home of the proposed Welsh Assembly, but the building was not required, with the rejection of devolution in that years referendum.  It was refurbished in 2001 with the plan of turning it into a major music venue, but had to be closed indefinitely, due to safety concerns.

Today is the feast day of Saint Seiriol (the fair)

Born c.494.  Seiriol was of Royal birth, his father was King Owain Danwyn of Rhos and his brothers, King Cynlas of Rhos and King Einion of Llyn.  According to legend, he and Saint Cybi were good friends and would meet regularly at the Clorach wells  near Llanerchymedd on Anglesey.  The direction of the way Seiriol walked to the meeting meant he had his back to the sun, thus, he was known as Seiriol Wyn (Seiriol the Fair).

 He initially lived in small hermits cell at Penmon but his two brothers decided  that this was too humble a residence for him and founded a monastery around his cell. Thus, Seiriol became the first Abbot of Penmon Priory and his cell and holy-well re still visible today.  In old age, Seiriol retired to the nearby island of Ynys Lannog (Priestholm), which became known as Ynys Seiriol in his honour, though it is now better known as Puffin Island.
